TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 570,432, dated October27, 1896. Application filed December 8, 1894:- Serial No. 531,258. (Nomodel.)

To aZZ whom, it may concern.-

Be it known that I, BERNARD GRANVILLE, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inType-IVrit-ing Machines, of which the following is a specification.

The invention comprises various features of construction and arrangementhereinafter described, and specifically pointed out in the claims.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a plan View of a sufficient portion of a type-writer toillustrate my invention. Fig. 2 is a section on line 2 2 of Fig. 1 withthe carriage in end elevation. Fig. 3 is a plan view of the guidewhenfarranged to use a ribbon for inking purposes. Fig. 4is a side viewof the guide of Fig. 3. Fig. 5 is a detail view of a guide fixed to themachine. Figs. 6 and 7 are detail views relating to the paper-feed.

The present invention is designed more particularly for application tothat class of type-Writers in which the type is carried uponlongitudinally-reciproeating bars, such, for instance, as the Rapid.These type-bars Ain the drawings are carried or supported by the twoconcentric plates B and C, the outer of which has openings 0, ofapproximately the size of the bars, While the front or inner plate isprovided with elongated slots Z ,corresponding in number to thediiferent banks of type. These slots permit of lateral movement or playin the type-bars, but hold them effectually against any verticaldisplacement, so that perfect alinement of the type is secured. In orderto center the type and insure its contact with the paper at preciselythe right spot for accurate spacing of the letters, I provide atype-guide D, which consists of the inclined plates (1 (1, having anopening d at the apex of a size to permit the type to pass through forprinting, the end of the type-bar fitting snugly in this opening. Theguide D is mounted upon the two arms E, which are preferably formedintegral with the inclined sides of the funnel, and are connected attheir lower ends to a swivel-support, which in the present instance isshown as a rod F, extending across the machine, and having its endssupported by the swivel-screws F in the frame of the machine, theconical ends of the screws entering corresponding recesses in the endsof rod. The arms E are inclined forward to the point where they aresecured to the swivelrod, so that the weight of the guide falls in frontof the said rod and tends to keep the guide normally away from theplaten in the position shown in full lines, Fig. 1. A proj ection orprojections e on the arms engages the under side of the platen-carriageguide G, or

corresponding part of the frame of the ma chine, and limits the forwardmovement of the guide, and thereby its distance from the platen I-I.Each type-bar is provided with a shoulder or shoulders a, which when thetype-bar is projected against the platen e11- gages with the edge of theopening d and carries the guide forward with it into proper positionadjacent to the platen, and as the guide is held securely against anyside movement, all the type are compelled to strike in exactly the sameplace relatively to the stationary parts of the machine. As the line ofmovement of the guide is at an angle to the majority of the type-bars,the utility of supporting the forward portion of the type-bars in theslots b will be plainly seen, as these permit the necessary sidemovement.

In order to provide for inking the type, I may provide an inking-rollerI, journaled upon a pivoted frame J ,carried by the main frame of themachine, and held by means of a springj normally over the opening cl.The type in its forward movement strikes this roller first and throws itto one side, as shown in dotted lines in Fig. 1, the face of the typebeing inked in its contact with the roller, and the side movement of theroller affords ample space for the forward movement of the guide topermit the imprint upon the paper.

Instead of using the inking-roller I may desired to use a ribbon, and inthis event it is only necessary to provide the guide with theretaining-clips D, one upon each side, for retaining the ribbon andguiding it across the opening in the guide. This construction isillustrated in Figs. 3 and 4.

In order to limit the baclnvard movement of the guide so that it willnot strike the paper upon the platen, I have provided the lower portionsof the guidccarrying arms with forwardly-proj ecting stops to contactwith the cross-bar 21, having eccentrically-arranged pins 22, journaledin the machine-frame and provided with turning-lniobs 28, by which theeccentric-bar 21 may be turned to present different parts of its surfaceas a stop to limit the backward movement of the guide-frame.

Instead of having a movable guide the same may be fixed, as in Fig. 5,by means of screws 24 to the machine-frame. The ribbon in this instancewould be moved to and from position across the opening of the guide by acarrierframe 39, oscillating vertically as in my United States Patent406,304, of April 25, 1893. The guide when arranged stationary, asdescribed above, would be fixed about onesixteenth of an inch from theedge of the platen. In this form, as in the one first described, thetypebars are allowed lateral play or automatic adjustment during theirstroke by contacting with the conveying sides of the guide and beingdirected thereby to the printing-point. The shouldered construction ofthe type-bars to prevent the bars from running through the guide-openingmore than a definite amount is unnecessary in this construction.slightly beveled on the sides. hen an inking-roller is used, a shield 40may extend around its rear side, and thus protect the paper of theplaten from splashes of ink which might be thrown by the type-bars.

In Figs. 6 and 7, I show details of an improved paper-feeding mechanism.The platen has the usual ratchet 41,to be operated by the pawl 42,carried by the line-space frame 43, pivoted at 44, and arranged to beoperated in the ordinary manner. This pawl is pivoted to the 1ine-spaceframe by the screw II, the end of which protrudes and contacts with theend of the detent-lever 45, carrying a pin 46, to engage the teeth ofthe ratchet and hold the platen in its moved position. This detent isdrawn into position by the spiral spring 47. The pawl has a second pin48, so that when the pawl is thrown out of action by pressing down itstail-piece 49 the pin 48 will engage the end of the detent-lever andthus throw this out of action also, so that the platen will now beperfectly free to be turned in either direction. Upon throwing the pushpawl into operation again the detent-lever will also fall intoengagement with the ratchet.

It will be noticed that when the push-pawl is tipped up out ofoperation, as in Fig. 6, the pressure of the arm 45 upon the pin 48 willbe directly in line therewith or slightly within the dead-center, sothat the pull of the spring 47 will hold the pawl 42 out of action.

Having thus described my invention, what I claim is- 1. In atype-writing machine, the combina tion of the movable type-bars arrangedto The forward ends of the bars are.
